The object of this thesis is to develop a reliable algorithm and soft\vare for em-level kinematic GPS (Global Positioning System) data analysis. To assess the accuracy of the softvlare, we use it to determine the trajectory of the aircraft during the surveys at Long Valley, California, in 1993 and 1995. This thesis covers the algorithm development, the modeling, and the software design. We impl...
Spectral domain optical coherence phase microscopy provides high resolution quantitative phase measurement. Using a common path Fourier domain optical coherence tomography system, this technique is capable of excellent phase stability of less than 1 milliradian and high imaging speed of up to several hundred KHz Aline rate. The limitation of 2π ambiguity restriction can be overcome by the use o...
Ramon Hanssen is assistant-professor in geostatistics, working on radar remote sensing for geodetic applications. Peter Teunissen is professor of Mathematical Geodesy and Positioning and authored the Lambda method. Peter Joosten graduated at the Faculty of Geodesy of Delft University of Technology. The authors are currently engaged in the development of ambiguity resolution algorithms for GPS d...
Kinematic carrier phase ambiguity resolution, i.e., on the fly, which is the key to cm-level accuracy differential GPS positioning, is investigated using high precision, single frequency, 10channel, C/A code receivers. The major characteristic of this unit is a narrow correlation spacing which improves code measuring accuracy to 10 cm and reduces code multipath interference. The high code accur...
This paper presents the derivation of the Ziv-Zakai bound (ZZB) for the localization problem in a MIMO radar system. The target is positioned in the near-field of a network of radars of arbitrary geometry. The radars have ideal mutual time and phase synchronization. The target location is estimated by coherent processing exploiting the amplitude and phase information between pairs of radars. An...
